Study the Process

Put process first and results follow.  

Remember the John Wooden process:

EDIRx5

E = explanation

D = demonstration

I = imitation

R = repetition

Study the run up and swing

Suggestions:

• Watch full screen (not on a cell phone)
• First note the general process.
• Note the hitting intent.
• Run it back multiple times, stopping and starting. 
• Where does the approach start (behind the ten-foot line)
• Note the footwork.
• See how she uses the back armswing to gain power
• Note the explosive attack and swing (volume up). 
• Consider using cell phone or YouTube video to study your attack.
• You can be a "big hitter," too.  

To improve your attack, study your process. Practice the run up without a set, then fire a tennis ball, then time with sets. Coaches value athletic explosion. Explosive athletes get the job done.
